3 . The contact lens system of claim 1 , wherein the processor shifts the part of an image to the central position of the said embedded display based on shift factor; wherein the shift factor indicates direction and extent of the shift of the image on the embedded display.
4 . The contact lens system of claim 2 , wherein the processor is further configured to:
track eyes gaze movement or head movement of a wearer of the contact lens and correlate the tracked eyes gaze movement and the head movement with a three-dimensional geometry of real world around the wearer of the contact lens, to determine a direction and extent of a shift of the image on the embedded display; or
track changes in eyes gaze direction of the wearer of the contact lens and correlate the tracked changes with a two-dimensional geometry of the embedded display to determine the direction and extent of the shift of the image on the embedded display.
5 . The contact lens system of claim 4 , wherein the shifting of the at least a part of the image is triggered in an event of a change in eyes gaze direction or in an event of reception of an predefined signal from the wearer of the contact lens.
6 . The contact lens system of claim 5 , further comprising one or more orientation sensors embedded in the contact lens substrate to determine the change in the eyes gaze direction.
7 . The contact lens system of claim 1 further comprising a depth sensor embedded in the contact lens substrate, wherein the change in eyes gaze direction is determined based on depth images captured by the depth sensor.
8 . The contact lens system of claim 1 further comprising a communication device embedded in the contact lens substrate, the communication device configured to communicate with one or more external communication device or with another paired contact lens.
9 . The contact lens system of claim 7 further comprising:
a processor to track changes in the environment using the output and to determine and recognize objects in the environment using the tracked changes to display the objects in focus on the embedded display.
10 . A contact lens system, comprising:
a contact lens substrate; and
an embedded display component forming a part of the contact lens substrate; and
rear facing image capture sensor, optionally coupled with rear facing emitter of invisible light;
wherein, rear facing image capture sensor is configured to identify and track focal length of the eye.
11 . A method for contact lens:
computing a shift, in an image disposition, on the embedded display; and
displaying at least part of an image at the central position of the embedded display to bring at least part of an image into focus;
wherein, the said embedded display component forming part of the contact lens substrate.
12 . A method of claim 11 ,
wherein the frame of reference is one of a two-dimensional frame of reference or a three-dimensional frame of reference.
13 . A method of claim 11 ,
wherein, the processor computes the shift of at least part of an image on the said embedded display based on the shift factor; wherein the shift factor indicates direction and extent of the shift of the image on the embedded display.
14 . A method of claim 12 ,
wherein the processor is further configured for:
tracking eyes gaze movement or head movement of a wearer of the contact lens and correlating the tracked eyes gaze movement and the head movement with a three-dimensional geometry of real world around the wearer of the contact lens, to determine a direction and extent of a shift of the image on the embedded display; or
tracking changes in eyes gaze direction of the wearer of the contact lens and correlating the tracked changes with a two-dimensional geometry of the embedded display to determine the direction and extent of the shift of the image on the embedded display.
15 . A method of claim 14 , wherein the shifting of the at least a part of the image is triggered in an event of a change in eyes gaze direction or in an event of reception of an predefined signal from the wearer of the contact lens.
16 . A method of claim 15 further comprising:
obtaining orientation information from one or more orientation sensors embedded in the contact lens substrate to determine the change in the eyes gaze direction.
